Just a thought from the other side of the fence!
When I don't 'listen' to my son, it's because I'm worried about what's going to come up in the context of my own 'perceived' inadequacies. If he's frightened of the dark, I can't admit that I'm frightened, too - I'm an adult and I have to instil confidence in him, otherwise I've failed. (!)
Ostrich, head, sand???
What's really puzzled me about how I've reacted to my child is 'why' when, by contrast, I spend my life 'dragging the truth' out of adults (myself included)!!!!!
But then a child is not an adult.
'Of course, you're not frightened' = "I don't want you to be frightened and if you insist you're frightened I'm going to get angry because I haven't had more than two consecutive hours' sleep for the past six years and I am desperate. It's 1am and being frightened of the dark is too big an issue to deal with right now. My needs are (finally) more important than yours but I think you're old enough to hack it - and if you're not, well, I'm going to collapse under the strain anyway and then I won't be able to look after you at all! So it's time to bite the bullet. Go back to bed."
I look back and see that from my son's point of view and I'm wracked with guilt; I'm an N! I see it from my own point of view and I begin to see that I'm a human being with my own 'needs' dealing with a son whose own needs, ironically, have always been diametrically opposed to my own.
But sometimes I don't listen to my son 'just' cos I've got a deadline of some kind or I'm preoccupied with some adult issue like making sure the meal is on the table in time for him to go and play with his friend. Or being at the bus stop in time for library storytelling hour.
It's almost impossible to 'live a life' and be constantly tuned in to a child - and once you stop tuning in, you lose the knack. Children are often 'objects' to be moved around because ultimately they aren't in a position to make their own life choices, they have to live their life in the context of their parents' lives.
It's also difficult as a parent to know WHEN the crucial times are to listen to a child. We don't read minds. But particular moments will be etched in our children's minds and we will forever be oblivious to the fact that it was an life-altering moment for that child. Most of the time, parents are just getting on with 'organising' lives rather than 'being' what our children hope we will be.
And so, when the (adult) child is feeling vulnerable - and it still feels like the parent is the one who holds all the cards for our emotional well-being and could cut us off at the knees so easily - then we don't make our parents sit down and KNOW that this is the time to think and feel and acknowledge and care. But perhaps the parent is then too horrified at what they might have to reveal (to themselves as well as to the child).
Supposing the hoped for 'of course I love you' turned out to be 'you were an inconvenience'. Then what? Do our mothers want to burn the effigy of 'good mother' (unlikely - they're hoping we still haven't found them out!!!) (Un/fortunately, my son found me out a long time ago!

)
If you want answers, I think you have to be very brave and very strong and consistently ask for times to talk about the past, set our your wares - explain how much you want to understand and then not feel devastated at sighs and rolling eyes and blame.
As I once said here (in my ACON role) 'my pain gets heard, too'!!! But you've got to be very, very determined in your own mind before you can begin to make yourself heard. And are you prepared for the pain the answers might bring?
And can you ask the questions behind the questions? (ie the question(s) that you
really want to ask???) Not about her mothering abilities, not about your fear - but about what love means to you and what love means to her and how it gets expressed.
Hmmm - that was one of those 'channelling' moments - it might be useful, but if not, please ignore!!!
